Abstract
A comparison has been made between differential-pulse polarographic and grphite furnace atomic absorption spectrometric methods for the direct determination of inorganic platinum in urine. Both methods were shown to suffer from matrix effects, but could be used to determine inorganic platinum down to 0.4 µg ml–1 in urine. A method is also described for the determination of inorganic platinum using adsorptive stripping voltammetry, but this could not be applied to urine analysis because of the nature of the electroactive response.Keywords
